For the deamon, write a for running by user root with chmod 700

#!/usr/bin/env python3
import sys
import yaml
from backupmysystemusb2usb.usb2usb import usb2usb

You can create a service systemd if you planed to backup your usb key evry day in the morning. You can wakeonlan from a raspberrypi or other technique

wakeonlan MACADRESS
crontab -e
# write your cron
sudo service cron reload

Now for create a daemon in startup (without console).

vi backupmysystemusb2usb.service



ExecStart=/usr/bin/sh -c "/your/working/path/ /your/working/path/config.yml"


Enable and start

sudo systemctl daemon-reload
sudo systemctl enable backupmysystemusb2usb

Then the service start on reboot. If you will test now the service :

sudo systemctl start backupmysystemusb2usb

Check the log (no detail just the command like dd)

sudo journalctl --unit backupmysystemusb2usb -n 20

You can go to check your ouput log file configured by config.yml

Now we have to create the shell return for non-root user

chmod 700

And write in file

#!/usr/bin/env python3
import yaml
from backupmysystemusb2usb.usb2usb import usb2usb
u2u = usb2usb('/path/to/your/config.yml')
